        2.      EXERCISE OF WARRANTS.

                2.1     GENERAL.

                (a)     This Warrant is exercisable in whole or in part at any
time and from time to time commencing on the Commencement Date (as defined
below). Such exercise shall be effectuated by submitting to the Company (either
by delivery to the Company or by facsimile transmission as provided in Section 8
hereof) a completed and duly executed Notice of Exercise (substantially in the
form attached to this Warrant Certificate) as provided in the Notice of Exercise
(or revised by notice given by the Company as contemplated by the Section headed
"NOTICES" in the Securities Purchase Agreement). The date such Notice of
Exercise is faxed to the Company shall be the "Exercise Date," provided that, if
such exercise represents the full exercise of the outstanding balance of the
Warrant, the Holder of this Warrant tenders this Warrant Certificate to the
Company within five (5) Trading Days thereafter. The Notice of Exercise shall be
executed by the Holder of this Warrant and shall indicate (i) the number of
shares then being purchased pursuant to such exercise and (ii) if applicable (as
provided below), whether the exercise is a cashless exercise.

                (b)     The provisions of this Section 2.1(b) shall only be
applicable (i) on or after the first anniversary of the Issue Date, and (ii) if,
and only if, on the Exercise Date there is no effective Registration Statement
covering the Warrant Shares (other than during a Permitted Suspension Period, as
defined in the Registration Rights Agreement). If the Notice of Exercise form
elects a "cashless" exercise, the Holder shall thereby be entitled to receive a
number of shares of Common Stock equal to (w) the excess of the Current Market
Value (as defined below) over the total cash exercise price of the portion of
the Warrant then being exercised, divided by (x) the Market Price of the Common
Stock as of the trading day immediately prior to the Exercise Date. For the
purposes of this Warrant, the terms (y) "Current Market Value" shall mean an
amount equal to the Market Price of the Common Stock as of the Trading Day
immediately prior to the Exercise Date, multiplied by the number of shares of
Common Stock specified in such Notice of Exercise Form, and (z) "Market Price of
the Common Stock" shall mean the Closing Price (as defined below) of the Common
Stock.

                (c)     If the Notice of Exercise form elects a "cash" exercise
(or if the cashless exercise referred to in the immediately preceding paragraph
(b) is not available in accordance with its terms), the Exercise Price per share
of Common Stock for the shares then being exercised shall be payable, at the
election of the Holder, in cash or by certified or official bank check or by
wire transfer in accordance with instructions provided by the Company at the
request of the Holder..

                (d)     Upon the appropriate payment, if any, of the Exercise
Price for the shares of Common Stock purchased, together with the surrender of
this Warrant Certificate (if required), the Holder shall be entitled to receive
a certificate or certificates for the shares of Common Stock so purchased. The
Company shall deliver such certificates representing the

<PAGE>

Warrant Shares in accordance with the instructions of the Holder as provided in
the Notice of Exercise (the certificates delivered in such manner, the "Warrant
Share Certificates") within three (3) Trading Days (such third Trading Day, a
"Warrant Share Delivery Date") of (i) with respect to a "cashless exercise," the
Exercise Date or, (ii) with respect to a "cash" exercise, the later of the
Exercise Date or the date the payment of the Exercise Price for the relevant
Warrant Shares is received by the Company.

                (e)     The Holder shall be deemed to be the holder of the
shares issuable to it in accordance with the provisions of this Section 2.1 on
the Exercise Date.

                2.2     LIMITATION ON EXERCISE. Notwithstanding the provisions
of this Warrant, in no event (except (i) as specifically provided in this
Warrant as an exception to this provision, (ii) during the forty-five (45) day
period prior to the Expiration Date, or (iii) while there is outstanding a
tender offer for any or all of the shares of the Company's Common Stock) shall
the Holder be entitled to exercise this Warrant, or shall the Company have the
obligation to issue shares upon such exercise of all or any portion of this
Warrant to the extent that, after such exercise the sum of (1) the number of
shares of Common Stock beneficially owned by the Holder and its affiliates
(other than shares of Common Stock which may be deemed beneficially owned
through the ownership of the unexercised portion of the Warrants or other rights
to purchase Common Stock or through the ownership of the unconverted portion of
convertible securities), and (2) the number of shares of Common Stock issuable
upon the exercise of the Warrants with respect to which the determination of
this proviso is being made, would result in beneficial ownership by the Holder
and its affiliates of more than 4.99% of the outstanding shares of Common Stock
(after taking into account the shares to be issued to the Holder upon such
exercise). For purposes of the proviso to the immediately preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "1934 Act"), except as
otherwise provided in clause (1) of such sentence. The Holder, by its acceptance
of this Warrant, further agrees that if the Holder transfers or assigns any of
the Warrants to a party who or which would not be considered such an affiliate,
such assignment shall be made subject to the transferee's or assignee's specific
agreement to be bound by the provisions of this Section 2.2 as if such
transferee or assignee were the original Holder hereof.

                2.3     CERTAIN DEFINITIONS. As used herein, each of the
following terms has the meaning set forth below, unless the context otherwise
requires:

                (a)     "Commencement Date" means the date which is six (6)
months after the Issue Date.

                (b)     "Closing Price" means the 4:00 P.M. closing bid price of
the Common Stock on the Principal Trading Market on the relevant Trading Day(s),
as reported by the Reporting Service for the relevant date.

<PAGE>

                (c)     "Reporting Service" means Bloomberg LP or if that
service is not then reporting the relevant information regarding the Common
Stock, a comparable reporting service of national reputation selected by a
Majority in Interest of the Holders and reasonably acceptable to the Company.

        3.      RESERVATION OF SHARES. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant

        (x) until the Final Lock-up Date, one hundred ten percent (110%) of the
        number of shares of its Common Stock as shall be required for issuance
        of the Warrant Shares for the then unexercised portion of this Warrant,

        and (y) thereafter, one hundred percent (100%)

of the number of shares of its Common Stock as shall be required for issuance of
the Warrant Shares for the then unexercised portion of this Warrant. For the
purposes of such calculations, the Company should assume that the outstanding
portion of this Warrants were exercisable in full at any time, without regard to
any restrictions which might limit the Holder's right to exercise any portion of
this Warrant held by the Holder.

        4.      MUTILATION OR LOSS OF WARRANT. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) receipt of
reasonably satisfactory indemnification, and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new Warrant of like tenor and date and any such lost, stolen, destroyed or
mutilated Warrant shall thereupon become void.

        5.      RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

<PAGE>

        6.      PROTECTION AGAINST DILUTION AND OTHER ADJUSTMENTS.

                6.1     ADJUSTMENT MECHANISM. If an adjustment of the Exercise
Price is required pursuant to this Section 6, the Holder shall be entitled to
purchase such number of shares of Common Stock as will cause (i) (x) the total
number of shares of Common Stock Holder is entitled to purchase pursuant to this
Warrant following such adjustment, multiplied by (y) the adjusted Exercise Price
per share, to equal the result of (ii) (x) the dollar amount of the total number
of shares of Common Stock Holder is entitled to purchase before adjustment,
multiplied by (y) the total Exercise Price before adjustment.1

                6.2     CAPITAL ADJUSTMENTS. In case of any stock split or
reverse stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation (where the Company is not the
surviving entity), the provisions of this Section 6 shall be applied as if such
capital adjustment event had occurred immediately prior to the date of this
Warrant and the original Exercise Price had been fairly allocated to the stock
resulting from such capital adjustment; and in other respects the provisions of
this Section shall be applied in a fair, equitable and reasonable manner so as
to give effect, as nearly as may be, to the purposes hereof. A rights offering
to stockholders shall be deemed a stock dividend to the extent of the bargain
purchase element of the rights. The Company will not effect any consolidation or
merger, unless prior to the consummation thereof, the successor or acquiring
entity (if other than the Company) and, if an entity different from the
successor or acquiring entity, the entity whose capital stock or assets the
holders of the Common Stock of the Company are entitled to receive as a result
of such consolidation or merger assumes by written instrument the obligations
under this Warrant (including under this Section 6) and the obligations to
deliver to the holder of this Warrant such shares of stock, securities or assets
as, in accordance with the foregoing provisions, the holder may be entitled to
acquire.

                6.3     ADJUSTMENT FOR SPIN OFF. If, for any reason, prior to
the exercise of this Warrant in full, the Company spins off or otherwise divests
itself of a part of its business or operations or disposes all or of a part of
its assets in a transaction (the "Spin Off") in which the Company does not
receive compensation for such business, operations or assets, but causes
securities of another entity (the "Spin Off Securities") to be issued to
security holders of the Company, then the Company shall cause (i) to be reserved
Spin Off Securities equal to the number thereof which would have been issued to
the Holder had all of the Holder's unexercised Warrants outstanding on the
record date (the "Record Date") for determining the amount and number of Spin
Off Securities to be issued to security holders of the Company (the "Outstanding
Warrants") been exercised as of the close of business on the Trading Day
immediately before the Record Date (the "Reserved Spin Off Shares"), and (ii) to
be issued to the Holder on the exercise




------------------------------------
1 Example: Assume 10,000 shares remain under Warrant at original stated Exercise
Price of US$1.50. Total exercise price (clause (y) in text) is (i) 10,000 x (ii)
US$1.50, or US $15,000. Company effects 2:1 stock split. Exercise Price is
adjusted to US$0.75. Number of shares covered by Warrant is adjusted to 20,000,
because (applying clause (x) in text) (i) 20,000 x (ii) US$0.75 = US$15,000.

<PAGE>

of all or any of the Outstanding Warrants, such amount of the Reserved Spin Off
Shares equal to (x) the Reserved Spin Off Shares, multiplied by (y) a fraction,
of which (I) the numerator is the amount of the Outstanding Warrants then being
exercised, and (II) the denominator is the amount of the Outstanding Warrants.

                6.4     ADJUSTMENT FOR CERTAIN TRANSACTIONS. Reference is made
to the provisions of Section 4(g) of the Securities Purchase Agreement, the
terms of which are incorporated herein by reference. The number of shares
covered by this Warrant and the Exercise Price shall be adjusted as provided in
the applicable provisions of said Section 4(g) of the Securities Purchase
Agreement.

        7.      TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION RIGHTS.

                7.1     TRANSFER. This Warrant has not been registered under the
Securities Act of 1933, as amended, (the "Act") and has been issued to the
Holder for investment and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                7.2     REGISTRATION RIGHTS. (a) Reference is made to the
Registration Rights Agreement referred to in the Securities Purchase Agreement.
The Company agrees to include the Warrant Shares of the Holder in the
Registration Statement (as defined in the Registration Rights Agreement), which
shall be filed and maintained effective as and to the extent provided in the
Registration Rights Agreement, all at no cost or expense to the Holder (other
than any costs or commissions which would be borne by the Holder under the terms
of the Registration Rights Agreement were the Warrant Shares deemed to be
Registrable Securities under that agreement).

                (b)     In addition to the registration rights referred to in
the preceding provisions of Section 7.2(a), effective after the expiration of
the effectiveness of the Registration Statement as contemplated by the
Registration Rights Agreement, the Holder shall have piggy-back registration
rights with respect to the Warrant Shares then held by the Holder or then
subject to issuance upon exercise of this Warrant (collectively, the "Remaining
Warrant Shares"), subject to the conditions set forth below. If, at any time
after the Registration Statement has ceased to be effective, the Company
participates (whether voluntarily or by reason of an obligation to a third
party) in the registration of any shares of the Company's stock (other than a
registration on Form S-8 or on Form S-4), the Company shall give written notice
thereof to the

<PAGE>

Holder and the Holder shall have the right, exercisable within ten (10) Trading
Days after receipt of such notice, to demand inclusion of all or a portion of
the Holder's Remaining Warrant Shares in such registration statement. If the
Holder exercises such election, the Remaining Warrant Shares so designated shall
be included in the registration statement at no cost or expense to the Holder
(other than any costs or commissions which would be borne by the Holder under
the terms of the Registration Rights Agreement). The Holder's rights under this
Section 7 shall expire at such time as the Holder can sell all of the Remaining
Warrant Shares under Rule 144 without volume or other restrictions or limit.

        8.      BUY-IN AMOUNT.

        (a)     If, by the relevant Warrant Share Delivery Date, the Company
fails for any reason to deliver the relevant Warrant Share Certificates, and
after such Warrant Share Delivery Date, the Holder who has exercised this
Warrant (an "Exercising Holder") purchases, in an arm's-length open market
transaction or otherwise, shares of Common Stock (the "Covering Shares") in
order to make delivery in satisfaction of a sale of Common Stock by the
Exercising Holder (the "Sold Shares"), which delivery such Exercising Holder
anticipated to make using the shares to be issued upon such exercise (a
"Buy-In"), the Exercising Holder shall have the right to require the Company to
pay to the Exercising Holder, in addition to and not in lieu of all other
amounts contemplated in other provisions of the Transaction Agreements, the
Warrant Share Buy-In Adjustment Amount (as defined below). The Company shall pay
the Warrant Share Buy-In Adjustment Amount to the Exercising Holder in
immediately available funds immediately upon demand by the Exercising Holder.

        (b)     The term "Warrant Share Buy-In Adjustment Amount" means the
amount equal to the excess, if any, of (i) the Exercising Holder's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (ii) the net proceeds (after brokerage commissions, if any) received by the
Exercising Holder from the sale of the Sold Shares. By way of illustration and
not in limitation of the foregoing, if the Exercising Holder purchases shares of
Common Stock having a total purchase price (including brokerage commissions) of
$11,000 to cover a Buy-In with respect to shares of Common Stock it sold for net
proceeds of $10,000, the Warrant Share Buy-In Adjustment Amount which the
Company will be required to pay to the Exercising Holder will be $1,000.

        9.      NOTICES. Any notice or other communication required or permitted
hereunder shall be in writing and shall be delivered personally, sent by
facsimile transmission or sent by certified, registered or express mail, return
receipt requested, postage pre-paid. Any such notice shall be deemed given when

of the federal courts whose districts encompass any part of the County of New

                          NOTICE OF EXERCISE OF WARRANT
                                 CLASS 2004-___(1)

         Holmdel, NJ 07733
         Attn: President

        The undersigned hereby irrevocably elects to exercise the right,
represented by the Warrant Certificate for the above-referenced Class, dated as
of ________________, 20___ , to purchase ___________ shares of the Common Stock,
$0.001 par value ("Common Stock"), of AMEDIA NETWORKS, INC. and tenders herewith
payment in accordance with Section 2 of said Common Stock Purchase Warrant, as
follows:

[ ]     CASH: $____________________________ = (Exercise Price x Exercise Shares)

        Payment is being made by:
                [ ]      enclosed check
                [ ]      wire transfer
                [ ]      other
[ ]     CASHLESS EXERCISE [if available pursuant to Section 2.1(b)]:

        Net number of Warrant Shares to be issued to Holder :         _________*

        * based on:   Current Market Value - (Exercise Price x Exercise Shares)
                      ---------------------------------------------------------
                                   Market Price of Common Stock
        where:
        Market Price of Common Stock ["MP"]         =                $_________
        Current Market Value [MP x Exercise Shares] =                $_________

        It is the intention of the Holder to comply with the provisions of
Section 2.2 of the Warrant regarding certain limits on the Holder's right to
exercise thereunder. Based on the analysis on the attached Worksheet Schedule,
the Holder believes this exercise complies with the provisions of said Section
2.2. Nonetheless, to the extent that, pursuant to the exercise effected hereby,
the Holder would have more shares than permitted under said Section, this notice
should be amended and revised, ab initio, to refer to the exercise which would
result in the issuance of shares consistent with such provision. Any exercise
above such amount is hereby deemed void and revoked.
